Keeping students engaged while learning programming is becoming more and more imperative. Of the several proposed techniques, gamification is presumably the most widely studied and has already proven as an effective means to engage students. However, there is a complete lack of public and customizable solutions to gamified programming education that can be reused with personalized rules and learning material. FGPE Gamification Service (FGPE GS) is an open-source GraphQL service that transforms a package containing the gamification layer -adhering to a dedicated open-source language, GEdIL -into a game. The game provides students with a gamified experience leveraging on the automaticallyassessable activities referenced by the challenges. This paper presents FGPE GS, its architecture, data model, and validation.
